Application led January 6, 1915. Serial No. 832.

T 0 all whom it may concern.'

Beit known that I, JOHN F. MEIssNER, a citizen of the United States, residing at Milwaukee, in the county of' Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Collapsible Tubes; and I do hereby declare the following tovbe a-ull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to collapsible tubes for containing tooth pastes, face creams, and similar compounds,.and one of the principal objects of the invention is to provide a collapsible tube having an angular opening for the discharge of the material resulting in several flat surfaces to prevent the. paste from rolling off the tooth brush, and this tube being provided with a cap fitted to the discharge nozzle of the tube, said cap being threaded and said nozzle being threaded by quick pitch threads, so that a slight movement of the cap will remove the same from the tube.

Another object of the invention is to provide simple, reliable and eiiicient means for closing the tube at the fillingl end.

The foregoing and other objects may be attained by means of the construction illus-l trated in the accompanying drawing, in v which- Figure l is a side elevation of a collapsible tube for containing tooth paste or other materials, made in accordance with this invention, Fig. 2 is a view showing the cap in section, and the discharge nozzle in elevation, Fig. 3 is a frontend view of the discharge opening showing the cap removed from `the tube, Fig. 4 is a sectional view taken on the line 4 4 of Fig. 1, and made on a larger scale, Fig. 5 is a sectional view taken on the line 5 5 of Fig. `1, and made on la larger scale, and Fig.` 6 is a plan view of the blank for the clasp or clip fitting the filling end of the tube.

Referring to the drawing, thelnumer'al Il.v

designates a collapsible tube such as is used for containing tooth paste,creams and similar compounds, and 2 is the discharge nozzle .fitted with a cap 3. The nozzle 2 is provided, as shown in Fig. 3 with a triangular v opening 4 for the discharge of the material within the tube l. The discharge nozzle 2 is provided with three screw threads of comparatively quick pitch so thatthe cap can be readily removed by al quick turn of the cap.

The clip 5 for closing the lling end of the tube consists of a piece of metal like'tin, or some ,'metal more rigid and of slightly thicker gage than the tube 1 which is provided with a series of slots 6 therein and said perforations are arranged upon opposite sides of a central line of the clip and are alternately disposed. When the tube 1 'is filled with the material, the lower ends of the tube are doubled up against the side of 'the tube, as shown in Fig. 4, at 7. The clip v5 is then bent upon the central line 8, as

shown in Fig. 6 and inserted4 over the doubled end 7, after which indentations or depressions!) are formed in the clip to crowd thematerial 7 through the perforations 6 on the opposite side of the clip.

From Fig. 5 it will be reediiy Seen that' the depressions are alternately on opposite si'des of the clip, thus insuring a firm clamp for the ends of the tube, since the layers 7 are crowded out 'of the perforations as shown at 10. l

Various changes may be made in the de-l tails of construction without departing from the spirit andscope. of the invention as defined n thepclaim. What is'claimed is g A collapsible tube'provided with a discharge opening vat one end and having the opposite ends of the tube doubled up against one of its sides, .a clip bent overthe .doubled end and provided with a series of perforai tions alternatelydisposed upon `opposite sides of a central line of said'clip-and dented upon one of the opposed sides in line with the perforations upon the other side to crowd the material of the doubled end into said perforations to firmly close said end.

v In testimony whereof I ax my signature in presence of two witnesses.
